The Tata Tiago can be considered as the car which saved Tata Motors from losing their market. The Tata Tiago offers a host of segment-first features, along with a brilliant design. The Tiago is also one of the best selling hatchbacks in the country. One of the many highlights of the Tata hatchback is the premium Harman audio system. The Tata Tiago features the diesel Revotorq engine, which although is not the smoothest, yet, it manages to offer decent performance and mileage in most driving conditions.
